DUMPING WAGON.

SIECIFICATION forming part of Letters Patent No. 413,566, dated October22, 1889.

Application filed June 22, 1889. $erial No. 315,158- (No model.)

To all whom it may concern.-

Be it known that I, BERNARD SCHRODER, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Dumping Wagons, which improvement is fully set forth in the followingspecification and accompanying drawings, in which- Figure I is a sideelevation of my improved dumping wagon, and Fig. II a top or plan Viewof the same.

My invention relates to improvements in dumping wagons and carts; andits object is to provide a simple, inexpensive and efficient devicewhereby the sliding box of a wagon, after discharging its load, may beeasily raised and replaced on the platform.

My improvement is especially adaptable to wagons designed for carryingcoal and similar freight. Being made suitably strong and substantial,they are consequently heavy and difficult to handle by the methodshitherto employed for the purpose.

The utility of my invention will be acknowledged by all who are familiarwith the fact that when the ordinary appliances are used the tail-boardof the wagon, by reason of its additional weight, is not replacedimmediately after the load is dumped, but remains unattached until theboxor body of the wagon is restored to its placeon the platform. It mustthen be lifted and attached by hand-an operation which overtaxes theability of any but an exceptionally strong man.

By the aid of my device the tail-board is attached before the rear endof the box is raised from the ground, and the extra labor is avoided.

Referring to the accompanying drawings, A designates a transverse shaftjournaled in brackets B, which are securely bolted to the front ends ofthe side rails C and also to the front cross-beam D of the platform orbedframe of the wagon. The forward ends of two chains E are attached tothe shaft and extend convergently and rearwardly to eyeplates F, whichare bolted to the front bar G of the sliding box H.

The object of employing two chains, attached as described, will beapparent. If but one were used, the line of draft would necessarily varyas the chain is wound on the shaft, and the box would be drawn more andmore sidewise at every revolution of the crank andpossibly become lockedbetween the side rails of the platform. In this device the chains are ofequal length, and when the shaft is turned the successive coils of thechains approach each other. The line of draft is thus made direct andcannot tend'to either side. The shaft is operated by a crank I, whichmay be detached when not in use and hung in a convenient position infront of the box.

J J and K K are anti-friction wheels turning with shafts that arejournaled in bearings secured to the side rails O and into the upperparts of their peripheries, about flush with the upper sidefof saidrails, and serving to facilitate the motion of the sliding box H.

L L are guard-arms secured to the side rails and preventing the box fromshifting laterally when in place.

M are curved arms that project upward from the rear ends of the siderails to engage against the lateral studs m on the box and prevent thelatter from slipping off the body. The upper parts of the peripheries ofthe anti-friction wheels are about flush with the upper sides of therails G.

The various advantages of this device are obvious. It will be observedthat it is complete in itself and may be readily applied to dumpingwagons made in the ordinary form. Any desired method of shifting the boxinto the dumping position may be used.

What I claim as new is- The combination, with the bed-frame of a dumpingwagon having the guard-arms L having lateral studs m and the eye-platesF, In testimony that I claim the foregoing I secured at the front of thebox at equal dishave hereunto set my' hand, this 15th day of 10 tancesfrom the sides of the body, and the June, 1889, in the presence ofWitnesses rearward converging chains E, of equal length,
